Description

4-Amino-3-Bromobenzoic Acid is a versatile halogenated aniline derivative that serves as a critical building block in advanced organic synthesis. Its bifunctional nature, featuring both an amino and a carboxylic acid group, makes it an indispensable intermediate for constructing complex molecular architectures. This compound is primarily sought after by research institutions and manufacturers in the pharmaceutical and agrochemical sectors for the development of active ingredients and specialty chemicals.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules requiring a brominated benzoic acid scaffold.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and other crop protection agents where the bromine atom and amino group impart specific biological activity.
• Dye and Pigment Manufacturing: Serves as a starting material for azo dyes and other complex colorants, leveraging the diazotization capability of the aromatic amine.
• Ligand and Catalyst Development: Employed in the creation of specialized ligands for metal catalysis and coordination chemistry due to its chelating carboxylic acid group.
• Polymer Modification: Acts as a monomer or functionalizing agent for engineering polymers, enhancing properties like thermal stability or introducing reactive sites.
• Research & Development: Widely used in academic and industrial R&D for exploring new synthetic pathways and creating novel chemical entities for screening.

Quality Control

Our 4-Amino-3-Bromobenzoic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets the high standards required for synthetic applications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture.
